I think the live service aspect is a bit played up though. You can play the game almost entirely solo, and it seems as though the 'peristent world' is more of a mirage than anything else.
Not a big fan of a BP and cash shop in a $70 game though, which is why I haven't purchased.
@hyper @Dasnap MTX is currently limited to cosmetic only and future battle passes.
It's blizzard though, so expect that to change with time.
